COMBINED DOOR HOLDER. AN D CHECK DEVICE.

Application filed December `19, 1925. Serial No. 76,430.

This invention has relation to a combined door holder and check of the suction cup type.

A main object is to provide asuction holder for swinging objects, such as doors, windows, and the like that will automatically engage the same when such objects are moved from one position to another to hold the same from further movement.

A further object is to provide a suction holder for doors and like structures that will also act as a cushioning device, that will not mar the surfaces of objects engaged, and which is provided with means whereby the suction may be readily broken to release the object held thereby when it. is desired to move or swing the object into a closed position.

Cushioning devices, such as ruhbertipped stops, .are now universally employed in building structures to limit the movement of door and Casement when swung to 'an open position, in order that the surfaces of the doors and adjacent framework will not be marred or disigured. While. such stops efiiciently perform their intended functions, yet no provision as far as am aware has een made to-automatically cushion the door when opened to its fullest extent and at the same time securely hold the same against accidental closure, except mechanical metal devices such as hooks, catches, and like devlces.

By means of the' present invention the door or other object is not only cushioned at the end of the opening movement but is automatically engaged and securely held in its opened position until manually released.

Une form of my invention is illustrated in the accompanying drawings, in which:

Fig. 1 shows an application of the device in connection with a swinging door. I Fig. 2 is a perspective view of the device.

Fig. 3 is a sectional view of the device enr gaged by a door.

Fig. l is a similar view showing another form of suction cup support.

` Fig. 5 is a side view of the device showing the automatic cup releasing means. y

Fig. 6 is a similar view with the cup in. section, showing a modified form of cup releasing ineans. f

Figs. 7-8 are front tace views of suction cups showing other modified cup releasing means.

ln an embodiment of the present invention, especially the forms as shown in Figs. 1 to 4 inclusive, 5 designates a holder support formed of a singble piece of strap iron, its ends 67, being ent in opposite directions to its body portion to form means of attachment and a support for the vacuum cup holder respectively. End 6 is provided with an aperture for the passage of a screw therethrough when the support is attached to the base board of a building partition 8, and the v opposite end 7 is also apertured for the passage of a bolt 9 for securing the cup shaped rubber suction holder 1() thereto. The thickcned base 11 of the catch is ,preferably countersunk as at 12 to chamber the bolt head, and its outer circular wall tapers outwardly towards its eriphery in order to render the same ilexib e and insure perfect suction when the door or other object to be held is brought thereagainst. .l

In'Figs. 4 and 5 the holder support is shown as formed of a wooden cylinder 13, provided with a bore 14 therethrough for the. passage of the securing screw 15, which serves to hold the suction cup catch 10, and

the cylinder 13 to the support.

When a door or other swinging object is brought against the cup holder, as shown in Figs. 3 and 4, the air therein will be expelled therefrom to form a partial vacuuln to firmly hold ,the door in engagement therewith. I have found in actual practice that the suction of the cup is so great that it requires considerable force to disengage the door from the cup when it is desired to close the same, and in order to render it comparatively eas of detachment I have provided a means or destroying the partial vacuum. formed in the cup on a slight pull on the door. In Figs. 2 and 6, the cup 10 is provided wi'th a rib 16v on its outer surface extending from its circular edge to its thickened base. By means of this rib when i a pull is exerted on the door, the edge of the cup adjacent the portion stiened by the rib will quickly disengage and thus destroy the` vacuum in the cup and insure a quick release. ln Fig. 5 instead of a rib, a. cord 17 is secured to a lug 18 formed on the outer` surface of the cup near its circular ed its Jfree end bein secured to the woo en c Ilinder 13. lin this term it will be apparent that as soon asa door which is held y the holder cup is pulled away from the same the cord 17 will hold the edgeof the cupat its point of attachment to quickly disengage the said edge of the cup from engagement with the door and thus destroy the suction of the cup.

`In Figs. 7 and 8 still other modified forms.

of cup releasing means are shown, the form shown in Fig. 7 consisting of a small air bleed opening 19 formed adjacent the circular e ge of the cup. It will be apparent that when a door is pushed into engagement with the cup that the circular flexible edge will be spread to cover the opening 19 and thus maintain a perfect cup suction. As soon as a pull is exerted on the door to close the same the circular edge will stretch suficiently to permit of an entrance of air through the o ening 19 to destroy the partial vacuum in t e cup to quickly release the door from engagement therewith. The form shown in Fig. 8 is substantially the same as in the preceeding ligure except instead of the opening 19 a notch 2O is formed in the c1rcular edge of the cup.

While I have shown the suction device secured to a building partition in the path of a swinging door, yet it will be perfectly obvious that the device maybe Secured to thJ door itself with equally satisfactory resu ts.

From the above description it will be apparent that I have provided a simple device that will effectively engage and hold a door against an accidental closing movement when Athe same has been opened, and will also act resilient cup shaped suction member and means for securing the same to a support, said suction member adapted to engage and hold a door against movement when brought in contact therewith, and means associated 'l with said suction member for destroying the suction therein when a pull is exerted on the door to close the same.

3. A suction door holder comprising a supporting member adapted for attachment to a stationary support, and a resilient cup shaped suction member Secured to said su porting member adapted to engage and ho d a door by suction when swung therea ainst, said cup shaped member having a b eeder opening formed therein, whereby to quickly destroy the suction in the cup when a pull is exerted on the door to disengage the same from the cup.

In witness that I claim the foregoing I have hereunto subscribed my name this 8th day of December, 1925.
